1 Claim.

My invention relates to a combined wall switch and electric clock andhas for its principal object, to provide a wall switch cover plate witha shelflike support for a small electric clock and said cover plateproviding a housing for electric conductors which connect service linecontacts within the wall switch with the contacts of said clock, thusenabling a clock to be conveniently connected to any wall switch andwithout the requirement of extension cords, plugs, sockets and the like.

A further object of my invention is to provide a wall switch and clockarrangement of the character referred to, which is simple in structure,capable of being readily installed on all standard embedded wall switchboxes, and which presents a neat and finished appearance.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangement of parts whichwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawing in which:

Fig. 1 is a perspective view of the combined wall switch cover plate andelectric clock.

Fig. 2 is a vertical section taken on-the line 22 of Fig. 1.

Fig. 3 is an elevational view looking against the rear side of the coverplate.

Fig. 4 is a cross section taken on the line 4-4 of Fig. 3.

Fig. 5 is a cross section taken on the line 5-5 of Fig. 3.

Fig. 6 is a diagrammatic view of the electrical connection between thecurrent supply line and the contacts of the clock.

Referring by numerals to the accompanying drawing which illustrates apreferred embodiment of my invention, Hi designates a conventional wallswitch box having the usual contacts I l for the supply line conductors[2, with a switch (not shown) in said line and which switch is operatedby a short pivoted arm such as l3, or by push buttons.

In accordance with my invention, the conventional switch box cover plateM of metal or plastics, provided in its rear face with a shallow recess[5 and projecting from the upper end of said plate is a shelf l6 adaptedto receive and support a. small conventional electric clock ll. Plate I4is provided with an aperture 18 for lever I3 and with apertures IQ, forscrews 20 which detachably secure said plate to the switch box 19.

Positioned within recess I 5 is a plate 2| of suitable insulation, forinstance, hard rubber, fibre or plastics and embedded therein areelectrical conductors 22, the lower end portions of which project beyondone edge of plate 2| so as to engage line contacts I l.

The upper portions of conductors 22 projects upwardly from plate 2|,through openings 23 formed in the upper portion of cover plate I4 andthus the upper ends of said conductors engage the clock contacts 24.Plate 2! which carries the conductors 22 is held in proper position withrecess it by the screws 26 which pass through apertures 25 in saidplate.

The electric clock IT may be secured to shelf it in any suitable manner,for instance, by means of a screw or screws such as 26 which passthrough the shelf into the lower part of the clock housing.

When plate 14 is secured to the switch box by means of the screws 26,electric current will pass from line wires l2, to and through conductors22 and from the latter to the clock motor contacts 24.

Shelf ltformed integral with the cover plate, provides a convenientsupport for the clock and the conductors within the recess in the rearface of the plate provide the necessary electrical connections for theclock, thus eliminating all exposed fittings such as extension cords,plugs and the like.

Thus it will be seen that I have provided a combined wall switch andelectric clock which is simple in structure, inexpensive of manufactureand very effective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved cover plate andelectric clock may be made and substituted for those herein shown anddescribed without departing from the spirit of the invention, the scopeof which is set forth in the appended claim.

I claim as my invention:

An electric clock mounting comprising a plate, a shelf projectingoutwardly from the upper end of said plate, there being aperturesthrough that portion of said shelf above said plate, there being arecess formed in the rear side of said plate, which recess communicateswith the apertures in said shelf, a plate of insulating material securedto said plate within the recess therein, a pair of electric conductorsembedded in said plate of insulation, the upper ends of which conductorsproject through the apertures in said shelf, the lower ends of whichconductors project laterally from the side of said plate of insulationand there being an aperture formed in the central portion of said plate.
